After the install dialog "finished", a temp\sketchup...exe controlled regular SketchUp.exe, which started up. Su looked normal, but I noticed the only plugin in su's Plugins menu is LtPlus (and it has a few submenus).
also windows desktop shortcut for "LTplus sketchUP PlugIN V.9.1" is same shortcut as prexisting regular SketchUp.exe shortcut.
SketchUp.exe has same filedate as many of the dll's. Properties says it is version 7.1.4871.0
This seems odd to me. And i don't know which other plugins have been hidden.
I'll probably fix this by using System restore.
I couldn't find much info about ltplus via google.

It says that ltplus plugin exports to DXF/3DS/VRML/STL.
(using su7.1 free on winxp)
Interesting notes about Intellicad based "cads", though these aren't su-related
Toolbars and/or Menus are destroyed, because the IntelliCAD-Version is not
AutoCAD-MNU/DCL-Compatible, uses absolute paths, or can't scale icons
Standard AutoCAD- or IntelliCAD-Dialogues, or Commands are missing
Complex Lisp-Routines don't work, because the IntelliCAD-Version uses an
encrypting Lisp-Interpreter, where Standard-Lisp-Functions are missing
